This second article of my mini series will step you and your LG G4 811 trough unlocking the bootloader, install the custom recovery TWRP and get root access with SuperSu.

Let’s start with the important part: It is your phone, you are responsible for everything you do with it. Don’t blame me if you make it worst trying to follow any of my articles. You do everything at your own risk. All data will be lost. Don’t forget to take a backup if you need anything.
